Although myxosporea have been known since the early nineteenth century, only about 1342 species belonging to 51 genera are recognized (Lore and Dykova 1992). All species of the class Myxosporea occur in ectothermic vertebrates, most of them in fishes (Post 1987). The present study deals with the prevalence of myxosporidia infecting six species belonging to three families of Nile fishes at Giza Governorate in Egypt. These fishes, which are of great economic importance, were identified as… 
Twelve myxosporean species of the family Myxobolidae infecting freshwater fishes of the River Nile, Egypt, with the description of four novel species
A survey of myxosporean parasites infecting four species of fishes from the River Nile in Egypt is conducted, finding one hundred and ninety-five out of 316 fish specimens with a percentage of 61.7 % were found to be naturally infected with these parasites.
Henneguya collaris sp. nov., (Myxosporidia), parasite of the Greenband Parrotfish Scarus collana Rüppell, 1835 (Actinopterygii, Scaridae) from the Red Sea, Egypt. A light and electron microscopic study
The present species is the first described histozoic myxozoan species of the genus Henneguya infecting the kidney of the greenband parrotfish Scarus collana (Actinopterygii, Scaridae) and the material described herein represents a new species.
Morphological re-description and phylogenetic relationship of five myxosporean species of the family Myxobolidae infecting Nile tilapia.
Morphological characteristics, host specificity and geographical distribution, tissue tropism, and molecular analysis of the partial sequence of small subunit ribosomal DNA gene revealed that the recovered myxosporean species described herein were genetically distinct from other myxozoan species but had 95% sequence similarity to M. cerebralis.
Testicular myxosporidiasis and ultrastructural characteristics of Myxobolus bufonis (Myxobolidae) infecting the Egyptian toad Bufo regularis (Bufonidae). A light and electron microscopic study
The present investigation introduced a new data for the recorded parasite observed by light and transmission electron microscopy and diagnosed as large clusters of macroscopic plasmodia embedded in the testicular tissue causing distortion at the site of infection.
Studies on Henneguyosis Infecting Wild African Catfish, ClariasGariepinus from Behera Governorate, Egypt
During a recent investigation of parasites infecting fishes inhabiting different Canals at Behera governorate (Egypt), a total of 200 sharptooth catfish were examined for the presence of Myxosporidian infections and H. branchialis was successfully identified.
Histopathological and ultrastructural studies of Henneguya suprabranchiae Landsberg, 1987 (Myxosporea: Myxobolidae) parasitizing the suprabranchial organ of the freshwater catfish Clarias gariepinus Burchell, 1822 in Egypt
A high intensity of infection with several plasmodia may cause a disturbance in the respiratory process of the infected catfish, leading to asphyxia and subsequently to weight loss.
Histopathological and ultrastructural studies of a Henneguya species (Myxozoa: Myxosporea) infesting the intestine of Clarias gariepinus from Benin (West Africa)
Histopathological analysis showed that the mass continuous development of the plasmodium produced thickening of the intestine wall and compressed neighboring tissues and destroyed villi and smooth muscle layers, which led to a high infestation by Henneguya sp.
Immature stages and re-description of Henneguya suprabranchiae (Myxosporea: Myxobolidae), an intestinal parasite of the catfish Clarias gariepinus in the River Nile, Egypt.
A new morphological description, supported by light microscopy photographs, is presented for various immature stages and for mature Henneguya suprabranchiae Landsberg, 1987 spores infecting the
Re-description of Myxobolus fahmii from the gills of Barbus bynni with new data on the precise infection site, histological impacts, and seasonality
The investigations enabled us to determine the precise infection site, which corresponded with the “filamental vascular type” and to provide, for the first time, information on pathogenicity and on the seasonal variation in the prevalence of M. fahmii in gills.
Revision of Myxobolus heterosporus Baker, 1963 (syn. Myxosoma Heterospora) (Myxozoa: Myxosporea) in African records.
The present study revises the taxonomy of M. heterosporus, using specimens isolated from plasmodia situated in the infected cornea of Oreochromis aureus, O. niloticus or Tilapia zillii inhabiting the River Nile, Egypt, to support that spores of a Myxobolus-like morphology co-existed with so-called tailed-spores in one plas modium.


A guideline for the preparation of species descriptions in Myxosporea
Guidelines for the preparation of a species description of myxosporean species are proposed and all important diagnostic features are listed and diagrams for size measurements are presented.
